Ivy Marwil
4 ounces (squares) bittersweet chocolate
1/2 pound unsalted butter (2 sticks)
2 cups sugar
4 large eggs
1 cup flour
2 cups miniature marshmallows
1 cup semisweet chocolate chips
1 teaspoon vanilla
1 cup chopped nuts 
Grease a 9 by 13 inch pan and preheat oven to 350 degrees. Melt chocolate and butter. Add sugar. Beat in eggs, one at a time. Stir in flour, add marshmallows, chips, nuts, and vanilla. Pour into pan and bake for 35-40 minutes or until barely done.

These are wet when they are done, so after they cool, I put the pan in the refrigerator for the brownies to firm up and then I cut them into small squares.
